Hi all,
Wonderful site this one!
I'm planning on doing a complete overhaul to the pool in my parent's house. It is a 28-year old pool that is seldom used but the pump is ran every day and the water is crystal clear. I enjoyed it while living there and now want my children to enjoy it as well. I want to replace the old sand filters with a big cartridge filter and also install a heater. There used to be a Teledyne Laars 250k BTU heater but it died many years ago. The filters also appear to have reached their life cycle. I think the heater was oversized for the pool.
Current configuration:
- 15k in-ground pool, concrete, two skimmers, 1 main drain, and 4 returns
- Around 400 sq. ft. surface area
- Daytime temp in Caracas is usually between high 70s and 80 F. In December-January, daytime temp is 70-75 F
- Altitude is 3000ft
Equipment:
- 2 Sta-Rite Waterford JWPA5FL-A pumps. The label says: 1-1/2 HP, SF 1.0, RPM 3450, KW 1.1, 120V. Can't find GPM curves for this pump and it isn't listed in the APSP database http://apsp.org/resources/energy-efficient-pool-pumps.aspx
- 2 small sand filters, I don't have details here
- 1 broken and fully internally rusted Teledyne Laars Millivolt 250K BTU heater
- 2-1/2 PVC pipes
- No chlorinator
We alternate between the pumps each day when filtering water. Some times the filters will dump debris back into the pool, even after backwashing.
This is what I have in mind for the upgrade:
- 420 sq. ft. cartridge filter
- Raypak PR156A 150k BTU heater
I read here that big filters are always good. I want to clean the new filter once a year. About adding a chlorinator system, I don't like the idea because I'm not sure what would be the long-term impact on the deck and surroundings (quite porous stuff).
These are my current questions:
Am I making an obvious mistake here? What do you think? Any recommendation?
Do I need a bigger heater? I like the Raypak PR156A because it is small and light and thus can be shipped to Venezuela much easier and safer than big heaters. Additionally, I read that this is a good choice in terms of reliability and durability. On the other hand, the heater requires a min of 20 GPM and max of 70 GPM. Will it be ok with the pump and filter combination?
Is my pump ok with the filter and heater? Do I need to change pump as well?
Many thanks in advance..
